BAG FILLING .um'

To all'urhom it may concern: i

Be it known that I. \VILLIAM Rt'Lisox.

citizen of the l'nited States. residing at Johnstown. in the county of Fulton and State of New York.- have invented certain new and useful Improvements in Bag Filling and Sealing llachines: and I do hereby declare the followin to be a full, clear, and exact. description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention consists in the novel features hereinafter described reference being had -to the accompanying drawings which illustrate the best form in which I have con a machine for automatically filling bags with measured quantities of material, and

Fig. 30 is a detail view of the glue or aste reservoir and the feed disk therein. Fig.' 31 isa de tail view of a part of the measurin "apparatus showin a modification thereo The main this instance of two end standards or frames 1, 1, provided with bottom flanged portions adapted to be secured by lag screws or other; wise to a table, trestleof othersup orting surface, a horizontal girder d toand connecting said standards their ends,- and a top bar 3 which is an upward curved portion 4.

"5 represents the hopp'e for the material which is supported from the main frame in this instance by vertical bars-6, 6 and braces 7, 7. The hopper is provided with an a I- hire 8 on one side communicating wit a supply pipe 9, through 'which the ma'terialgis introduced, and the supply" aperture 8 is coir-. troll-ed by a sliding gate 10, operable from the interior of the hopper by means of a projection 11. The front wall of the lio'pper'is' provided with a swin in dofor5coverin an a erture through wiic access can be ha to t ie interior to adjust gate 10, or the measuring cups'hereinafter described. 1 3150; ,prefer to provide a-transparent panel "53in the hopper as shown so that the operator can see if material is in the hop er. The ho per is also provided with'a. ownwardly' 1-. rected tangential discharge spent 12, girlhi'ch Frame of the machine consist cured to the top jaw as shown in Fig. 18

vfor withdrawing any dust which may arise from the filling of the bags. A horizontal shaft 15 extends throughthe side walls of the hopper and is provided with a plurality of radial arms 16, two being shown, carrying at their outer ends adjustable measuring scoops or buckets 17 secured ,to the ends of said arms by straps. 18, or in any other desired way. The scoops or buckets are best shown in Figs. 6, 7 and 8 and consist each of a cylindrical shaped vessel closed at one end and havingits walls projecting farther on the side adjacent to the shaft than at other portions. Each scoop is preferably provided. with a false bottom, 19 adjustable by means of a screw 20, to vary the capacity of the vessel, and the screw 20 is preferably provided with a friction spring or brake 21 (see Figs. 7 and 8) which binds against the wall of the vessel, and holds the screw in its adjusted position.

On the outside of the hopper, the shaft 15 is provided with a sprocket wheel 22 connected by a chain 23, with a sprocket wheel 24, on a cross shaft or stud 25, and connected by a miter pinion 26, with a similar pinion 27 on the main shaft 30, of the machine which extends longitudinally of the girder 2, and through one of the end standards 1.

I prefer to give intermittent rotary motion to the. shaft 15, and which I accomplish by using a mutilated pinion 27, on the main shaft and omittin duce the desired intermittent motion. The sprocket chain is conveniently held taut by an idle roll 28, on an adjustable slide or plate 29, secured to the top-bar 3. It is obvious, however, that the shaft 15 might be driven in other ways.

Beneath the hopper is the filling chute for guiding the measured quantity of material delivered by one or other of the scoops 17, to the spout 12, into the bags. This chute which is best seen in Figs. 13 to 20 inclusive, comprises a fixed jaw 31 and a movable jaw 32, carried upon a horizontally reciprocating slide 33, which is mounted in a suitable slide bearing atthe upper end of a post 34, se-

bar 3 of the frame. The fixed jaw is preferably formed as illustrated in Fig. 19, and is provided with lateral flanges 35 increasing in width toward the upper end of the jaw, and secured rigidly to a vertical transverse fulcrum plate 36, which is formed integrally with or attached to the slide 33. The movable jaw 32 is also provided with lateral flanges 37, increasing in width toward the top and adapted to fit within or overlap the flanges 35 of the fixed to prevent the material from spilling laterally. The movable jaw is pivotally mounted .or hinged with rea number of teeth to pro- '13 to 16) which holds it'normally spect to the fixed jaw and prefer to pro-. vide it with a laterally projecting lip or arm 38, preferably formed by bending. into horizontal position an integral piece of metal forming a continuation of the movable'jaw, and forming an angle therewith which engages the'top edge of the fulcrum plate 36, the movable jaw being held in position with respect to the fulcrum plate by curved bolts shaft 30, as shown in Fig. 3, said jcam being timed to move the chute horizontally atthe required points in the cycle/of operation of the machine. The upper end of the lever 41 is suitably connected with the slide 33. In

this instance the lever is bored out near its upper end, toreceive a longitudinally movable extension piece 44 (see. Fig. 13) which is provided at its upper .end with a yoke 45 pivotally connected to the slide by a pin 46, the pin being held in position by a plate 47 secured to one side of theyoke byia screw, as'shown in Fig. 13. The yoke 45. is provided with a horizontal slot engaging the pin 46 and the rear face of the yoke is rovid ed with a spring 48 'which bears agalnst the end of the slide 33, .and presses it to the right (Figs. '13 to 16) thuspermitting a v slightly backward yieldinglof. the chute if necessary when it encounters the endmost bag in the bag magazine, as hereinafter described. 4

The movable jaw is operated in a"direcf-Y; tion away from'the fixed jaw by means ofai plunger 49 (see Fig. 21) extending through the slide support, and having a head 50.

above the same andimmedi'atelyj beneath the" arm 38 of the movable jaw." The plunger 49 is provided With-a retracting spring '51 and its lower end isjthreaded to receive an adjustmg sleeve 52' which;, is'fadjustable thereon and is secured'in' adjusted position by a set nut 53. The plunger is operated at the proper time as hereinafter described. The movable jaw 37 is also provided referably with a retracting spring 54: igs.

close a bracket secured to one of the standards 1, i

the outer end of said lever extending preferably beyond the point of pivoting and provided with a counter balance, in this inment with t e lever for accurately a usting the same and being secured thereto by v edges inclined outwardly from top supports 65.

' thereto by light spring arms 76 a set screw 62.

' The-bag magazine is illustrated in detail in Figs. 9 to 12 inclusive, and is constructed as follows. The lever is bifurcated at its inner end and the bifurcated portions 63 are provided with transverse dovetail grooves 64 which receive the correspond-' inglyf shaped lower ends of two vertically disposed supports 65, 65 adjustable later-all? in said grooves to accommodate bags of'd' ferent widths, andlocked in their adjusted positions by screws 66. The bag magazine itself comprises two side plates having curved portions 67 which are made very thin attheir lower ends, where theyengage the stack of bags and arms (38, the latter being pivoted to the upper ends of the vertical These side plates are connected by cross rods'69,69 extending through apertures in said side plates and secured set screws 70 so that the plates may be adjusted laterally toward and from each other to accommodate bags of. different width. 71 represents a curved bottom platedisposed between the curved portions 67 of the plates, and supported upon the lever 60 by brackets 72,73, for supporting the bags. The vertical supports ()5 are each provided with a retaining plate 71 secured thereto by screws passing through horizontal slots in said plates to permit lateral adjustmentthereof, and said plates have their inner to bottom so as to engage the upper portions only of the outermost bag of those held in the magazine. and prevent the bags from escaping therefrom. In order to force the bags in the magazine toward the retaining plates 74, I provide a plunger 75 pivotally connected with the side plates of the magazine. and in this instance pivotally mounted on'one of the crossbars (39. This plunger is provided at its lower end with a pair of crossed in the form of an X and secured centrally to the end of the plunger thus providing four points of contact on the rear-most bag in the magazine. The plunger 75 is also provided with means for securing it'a'djustal-rly inrel-a'tion mane side plates, and for this purpose I prefer to provide the plunger with a cross bar 77 provided at each end with a spring actuated pin or tumbler 78 (see Fig. 10) adapted to engage one of a row of depressions or. recesses 79 arranged on the inner face of the adjacent side plate. The outer .end of plunger 75 is provided with a handle to facilitate its adjustment, and also for elevating the plunger and side plates when it is desired to place a sup )lv of bags in the magazine. At. such time the plunger may be \urned'to the position shown in dotted lines (Fig. 9) and 1 made to engage the rear weight of the plunger and side edge of the curved bottom plate or bracket 73 to hold the parts elevated while the bags are inserted. It will be obvious that when the plunger is placed in the position shown infull lines (Figs. 9 to 12) the spring fingers 76 will bear against the real-most bag with the lates. .If more weight is required an additional removable weight 80 may be supported upon the outer cross bar 69 as shown 1n the drawings or otherwise secured to the plunger and side plates. I

The lever 60 carrying the bag magazine is raised and lowered at the required times by means of suitable connections with the main shaft 30. In this instance the shaft 30 is shown provided with a cam 81 (see Figs. 1 to 5) having a cam groove 82 on one face, (Figs. 3 and 4) which is engaged by a roll 83 on a vertically movable slide. bar 84, provided with a slotted portion 85 engaging the shaft 30. The n per end of slide bar 84 is connected by a link 86, with one end of a walking beam 87 the opposite end of which is connected by a: link 88 with .the lever 60.

Below-the bag magazine is a horizontally disposed and. revoluble drum or carriage 90 substantially circular in-plan, but rovided at'intervals around its peripheral ace with flattened portions 91 curved outwardly at their lower ends, and below said flattened portions is an annular supporting rail or flange 92 projectin from the drum to sup. port the lower en 5 of the filled bags. I prefer to make this rail vertically adjustable to accommodate bags of different heights and to this endit is provided with vertically slotted In or cars 92 through which screws pass whic secure itto the drum. The drum is mounted to rotate with a shaft 93, mounted in a bearing, secured to the horizontal frame girder 2, and is driven by means of a pinion 94 onthemain shaft 30 which engages an annular gear rack 95 formed integrally with or secured to the bottom of the drum (see Fig. 24:).

96 represents a. guiding chute through which the filled bags drop from the bag filling chute upon the horizontal supporting vrail 92 of'the carnage or 'dr'um. The chute 96 terminates at about the level of the top of the carriage, and the bag is guided to the rail 92 and momentarily supported by a spring shifting plate 97 secured adjacent to its upper edge to a lever 98 pivoted to the frame, the lower end of the lever being provided with a friction roll 99 or projection engaging a groove in a timed cam 100 on main shaftBO (see Figs. 24 and 28) As the carriage is continuously rotated it is necessary to position each of the filled bags with respect to one of the flattened bag engaging faces of the carriage. These Fig.

. normally holds the positioning devices. in this instance, comprise a positioning stop or dete'nt101. mounted rying detent 105 mounted in the carriage adjacent to each of. the said flattened faces 91. The positioning detentconsists of a horizontally disposed sliding rod 101 (Figs. 2-1, 526. 28 and 29) engaging a suitable guide 101 adjustably secured to the frame and having shifting plate 97 to engage the edge of the bag. when the detent is projected and holdcarrying detent 105 (one of which is shown in detail in Fig. :29) extending through a recess in the wall of the drum or carriage 90. atthe rear edge of each flattened face 91. the inner end of the carrying detentbeing connected to a cam engaging lever 106 provided with a retracting spring 107 which detent 105 in retracted position. The detents 105 are each projected justbefore they reach ,a position in line with the rear edge of a filled bag as it lie upon the supporting rail 92 and spring shifting plate 93. by means of a stationary cam 108. secured to the frame of the machine within the drum or carriage as shown in Fig. 29. and at the instant the detent is projected the positioning stop or detent 101 is retracted out of the path of the bag. leaving the bag free to be carried by the drum. and the bag is also shifted by the shifting plate 97 into engagement with the adjacent tlat face 91 of the carriage,

Fpon the top and outer edge of the carmountcd a plurality of folding blocks 110. one above each of the Hat faces 91 of the carriage. Each of these blocks is connected by alink 111. to one end of an L-shaped actuating lever 11:2. the op posite end ofwhich carries a roll 11?). The link 111 and lever arm 112 are brought into a straight line to positively lock the folding block when the latter is swung down over the adjacent bag receiving face 91. as shownat the right in Fig. 24. and said folding block is raised to bring its inner face into a substantially horizontal position while passing the chute 5H? and the paste or glue applying mechanism (hereinafter described) by means of a stationary cam 1H- (shown in detail in r1 age a re pivotal l v ,on the frame of the machine, and a' carone end located adjacent to the spring The other end of the detent 101.

The carriage 1S proy'lded with a 22) which has an exterior curved surface to engage the inner face of theroll 113 of each folding block and successively raise said blocks. The cam 114 is supported from a bracket 115 c to which the cam 108 is also preferably attached, and the cam 114 is also provided with an extension 116 carrying a yielding pressure applying blade 117 whlch is preferably formed of backed up by a spring 118 if desired, as shown in Fig. The yielding blade 117 engages the outer face of each of the rolls 113 successively, and thereby positively forces the folding it, as before described, causing it to fold the flap of the bagafter the paste or glue has been applied'as hereinafter described. The blade 11? will yield in case two or more plan, Fig.

in which case the locking plate locked, thus avoiding straining the parts. I

In order to prevent the folding blocks 110 from striking the I in raised position (as shown at the left in Fig. 21), I prefer to provide a stationary guard plate 120 extending over the folding plate adjacent to chute 96 as shown best in that figure. the shifting plate 97 for fol ding,

is operated as before described to shift the bag into position on vthe carrier (see Fig. 21) into the position shown in dotted lines. it will pass under the folding block which is momentarily opposed to it. and thereby press the lip of the bag beneath the same, and bend the lip into horizontal position as therein shown. For

convenience the bag is represented through-- out by the letterB and the lip is lettered 7/. 3'-

The rota r carriage 90 is also provided adjacent to each of the folding blocks 110 with a pressure block 121 (one of which is shown in detail in Fig. 25) mounted on the end of edges of the bags while 91' It will also be seen that when a slidc'or bar 122, carrying a friction roll or H stud 1:23. the outer face of the pressure block being preferably provided with a cushioning surface 12-1- of rubber, leather or other suitable material. The pressure blocks 121 are arranged to be projected through horizontal apertures 125 in the flat portions of the wall of thedrum 90. and the slides 122 are held in suitable radially disposed guides 126 on the top face of the drum or carriage. see- Fig. 26. The friction rolls or studs 123cmgage a cam groove 12? in the lower face of a stationary cam plate 128 (see Figs. and 21) secured rigidly to the top plate 3 and provided with a central aperture e11- gaging the top of shaft 93 upon which the carriage rotates, The cam groove 12? is timed so' as to project the slide 192 after the folding block has been depressed. and while it is held by the spring blade HT. thereby bringing the cushioned surface 1;!

permitthe discharge of the bag, thus giving sufficient time for the paste or glue to set.-

' The paste or glue applying devices are shown best in Figs. 26, 27 and 30 and are adapted to apply the adhesive material in a thin continuous strip across the frontfold of the bag" just beneath its to edge, in position to engage the flap b when t e latter is folded; The entire mechanismis mounted on a horizontal s lde 130, in this instance, supported by and having a slidin engagementwith the horizontal girder 2'. his slide 130 is positively reciprocated by suitable means, and is shown provided with a stud or frictio'n roli- 131, engaging a cam groove a rotary'cam 132, secured to the shaft 30, and timed to reciprocate the slide at the proper intervals in the'cycl'e of operation of the -machine.

'The slide 130 carries a receptacle 133* for the adhesive material whichis' provided with a cover consisting of flat plates 134, 135 each providedvwitha lug 136, thmu'ghwhich extends an adjusting thumb screw. 137 engaging a threaded aperture in a lng138'seclir'ed The adjacent edg'esof plates 134, 135 are recessed to form a slit through which a distributing'disk 140- ex lates ma be adjusted lateral y by means "their re- 1 spectiveset screws,- to regulate the widthof thisslit, andtherefore the amount of'a-d- 'hesive material on the faoeof the distribut ing: disk 140.

As soon as the material hasjbeen' deposited in the bag, theslide 33 is actuated by-its cam so as to draw the filling chute rearwardly with the filled bag which will pass between the retaining plates-74 of the bag magazine and the 'bag is then heldwithiding chute 96, as-shown in Fig.16. The ever 60 carrying the "bag magazine then starts to descend, releasing the plunger 49, which is retracted -by its spring 51, thus releasing the movable jaw 32, whichcloses-upon the fixed jaw, releasing the bag and permitting it to fall through chute 96 to the position-shown in full lines Fig. 24, where it is arrested by the rail 92 of. the carriage,- is held in substantially -vertical position by the spring shifting plate 97 and is prevented from lateral movement by the positioning stop or detent 101, until one of the flat faces 91 of the carriage is opposite -the bag when the detent is projected'to engage the other edgeof theba'g, the'positioning stop is retracted and the shifting plate 97. is actuated by its cam to throw the bag over against the flat face of the carriage as shown in dotted J lines withthe flap b beneath the folding block 110, and holds it lightlyin that position as it is Inoved'laterally with the carriage until itis engaged by one pair of the pasting and scoring segments. The lower Z end of the bag is alsolightly held by the curved guide 161 near the bottom to prevent it from sl'ipping'ofi ofthe-rail 92. While' the bag 'justreferred to is being carried around by 'thecarriage, other bags are suc- 1 cessive ly filled and discharged into the guiding chute 96'as previously described, so that the-o eration of the machine isicontinuous. 's a bag leaves the positioning stop 101, itpasses toward the front of'the 1 machine,-.where it is engaged'by one-pair ofthe pasting and scoring se 'ents -157, 158 as previously described,.-an is lightly ged by -the' edge of thedisk 160, thusen ho ding it until',-the"fo1ding.b1dck is turned 1 down to'seal the flap, the upper end of the bag and the .fo1ded' flap; eing pressed between the folding block and the cushioned face of the pressure block as before described to insure the proper sealing, after whichthe 1 bag is carried around to the'rear side of the machine when the folgiling .block is raised,

the pressure block retmcted, and the sealed .bagis're'moved lziy;- the-blade 174: vand falls upon: the carrier V whichbyings it to the 1 usages front of'the machine and it is discharged- 7 by the brush 1T6 upon the delivery chute 175. i

In some instances where itis-de'sired to fill the bags with a measured quantity of a material which is apt to pile up at the mouth of the measuring cups or vessels and cause slightly unequal amounts to be delivered thereby, I employ the device shown in Fig. 31 to equalize the quantity in the measuring cups or vessels as far as possible. This consists of a scraper 190 in the form of: a

bail mounted on a rock shaft 191 extendin throu h the hopper (here lettered 5) an provi ed with an arm 192 connected pivotally with a bar 193 having a. forked end 194 to engagethe shaft '15 to guide it, and a stud or roll 195 to engage a double cam 196 on the said shaft, a spring 19? serving to retractsaid bar 193 and hold the roll in engagement with the cam. As each of the measuring cups or vessels passes the bail 190 the latter is operated by the action of the spring and cam to sweep over the top of the rial will be deposited on any part of thecup. 'and scrape 011' any sur his material which falls to the bottom of t e hopper 5,

thus'insuring an even feed of thematerial which can be accurately regulated by adjust ing the capacity of the cups as before described, said cups being identical in construction with those previously described.

I do not desire to be limited to the exact details of construction herein described and shown as slight variations may made therein without departing from the invent-ion.-

It will noted that the segments for applying the adhesive material are located in the horizontal plane of the apertures or slots 125 in the carriage through -which the pressure blocks are projected. It,therefore, follows that if any of the bag engaging faces of the carriage should fail to receive a bag for any .reason, the operation of the paste wheel will merely bring it op ite to said aperture or slot 125, and no a hesive matecarriage. This is an im 'rta-nt point, as it saves the time which won d'otherwise be lost by sto ping the machine to clean the parts from the paste or glue.

In'some instances I prefer to provide the vertical bars 65, 65 of the bag magazine withstrippin arms 65, 65 secured thereto and adjustab e vertically thereon. These strippingl arms asshown, extend on opposite sides f t e filling chute, and as the bag magazine "descends they will assist in removing the bag from the chute. These stripping arms may be dispensed with in some cases especially where material having considerable weight is charged into the bags, but when a very small quantity of light material is put in each bag these fingers insure the removal of each bag.

The specific form of measuring device shown and described is not claimed herein as it forms the subject matter of a'di'visional application for Letters Patent of the United States filed by me Nov. 30, 1908 and'given Serial No. 465,118. p v
